Editing Stipule (section)

== Types ==
=== According to duration ===
The three types of stipules according to duration are [[Dehiscence (botany)|caducous]], deciduous and persistent. Caducous stipules fall off before the leaf unfolds, while deciduous stipules fall off immediately after the leaf unfolds. Persistent stipules remain attached to the plant.<ref>{{Cite book|url=https://archive.org/details/botanysoutherns00darbgoog|quote=Caducous, Deciduous and Persistent stipules.|title=Botany of the Southern States|last=Darby|first=John|date=1860-01-01|publisher=A.S.

=== According to shape, size and position ===
Stipules can be considered free lateral, adnate, interpetiolar, intrapetiolar, ochreate, foliaceous, bud scales, tendrillar or spiny.

A stipule can be fused to the stem, or to the other stipule from the same node.

A stipule is "adnate" if it's fused together on part of the petiole length, but the anterior is still free.

A stipule is "interpetiolar" if it is located in between the petioles, as opposed to being attached to the petioles, and generally one stipule from each leaf is fused together, so it appears that there's just one stipule between each leaf.<ref>{{Cite book|url=https://books.google.com/books?id=9HOmOElZL6IC&q=stipule&pg=PA33|title=How to Identify Trees in Southern Africa|last1=Wyk|first1=Braam Van|last2=Wyk|first2=Piet Van|date=2007-01-01|publisher=Struik|isbn=9781770072404|pages=33–36|language=en}}</ref>

A stipule is "intrapetiolar" if it is located in the angle that is between a stem and a petiole. In this case, the two stipules generally form together and appear to be one stipule.

A stipule is "ochreate" if a single stipule appears to be a solid tube that goes all the way around the stem.

A stipule is "foliaceous" if it is leaf-like. These are generally used to photosynthesize.

A stipule is considered a "bud scale" if it is hard or scaly and protects leaf buds as they form. These generally fall off as soon as the leaf unfolds.

A stipule is considered "tendrillar" if they are long thin tendrils, and are generally used by climbing plants.

A stipule is considered "spiny" if they are long and pointy. These are generally used to deter animals.

A stipule is considered to be "abaxial", "counter" or "leaf opposed" if it is located on the opposite side to where the leaf meets the stem.<ref name=":0" /><ref>{{Cite news|url=http://www.publishyourarticles.net/knowledge-hub/science/what-are-stipules-and-what-are-its-types/4494/|title=What are Stipules and what are its types ?|date=2012-02-14|work=PublishYourArticles.net - Publish Your Articles Now|access-date=2017-04-04|language=en-US|archive-date=2021-03-02|archive-url=https://web.archive.org/web/20210302180420/https://www.publishyourarticles.net/knowledge-hub/science/what-are-stipules-and-what-are-its-types/4494/|url-status=live}}</ref>
